Hypertension is an increase in Blood pressure in the arteries. An increase in the systolic and diastolic blood pressure up to the level of more than 140mmhg and more than 90mmhg respectively is referred as hypertension.

Hypertensive emergencies arise when severe increase in Blood pressure occurs i.e. systolic BP of more than 180mmhg and diastolic BP more than 130mmhg. This hypertensive crisis has an increased risk of end organ damage. Symptoms of hypertensive crisis encompass severe chest pain, severe headache, severe anxiety.

Essential Hypertension pathophysiology explains the underlying mechanism as circulating vasoconstriction causes an abrupt increase in systemic vascular resistance and abrupt increase in Blood pressure is also noted. As a result, endothelial damage takes place and autoregulatory function is lost, causing end organ ischemia.

Acute coronary syndrome, subarachnoid Hemorrhage, hypertensive encephalopathy acute renal failure, and several other diseases are discussed differential diagnosis of acute Hypertension.

Along with Electrocardiography and Clinical Radiology techniques, some laboratory tests such as complete Blood count, pregnancy test, toxicologic testing are carried out for the proper diagnosis.

Variety of treatment options are available including hydralazine, nitroprusside, and hydralazine.
